Seeking options for St Louis MO area battery repair?

Anyone know of any reputable hybrid battery repair shops for 2010 Prius?

 

Hey there Bisco,
Im looking for an initial diagnostic as my modules are reading all good volts at ~7.6; the rest of the system (ex. computers) Im unclear to diagnose and address my yellow triangle that deters from DRIVE or REVERSE.
Once the technician diagnoses, then cheapest options from there on...
- parts replacement/ swap
- rebuilt exchange
- new lastly

 

infact i had a nasty little spark session earlier today
that fried my flex head 1/4" socket (wrench is OK, but socket is done) and welded 1x bolt to a battery module ( i cannot extract nut off)
i lucked out big time
i will never use flex head sockets while working with electricity again

after a quick break, i proceeded to test the modules;
all are reading fine at ~7.6 volts
now its the ancillary components I am ignorant of

 

UPDATE. the Prius is back up and running!
I replaced the battery module with 1x new mail order ($18) along side new order of nuts ($13/bag-o-100) and 1x new copper bus plate ($2)
i recycled the orange plastic protector, by exacto-knife-carving it out and freeing it from being trapped underneath a melted in copperplate-nut (see pic above)
pretty strait forward with module removal and replacement
im so excited Prius is back up and running!
LESSON LEARNED- don't use a flex head socket wrench around electricity
